Abstract

Un dispositif modulaire (12) comprend une partie base (14) et une partie détection de couleur (16). La partie détection de couleur est dotée d'une face, d'un décalage de source lumineuse commandée depuis la face pour définir un intérieur, la face conçue pour engager une surface de cible autour d'un périmètre de la cuve du dispositif, empêchant la lumière ambiante d'y pénétrer. Un détecteur de couleur reçoit la lumière réfléchie de la surface cible et génère des signaux de sortie représentatifs d'une couleur de surface. La partie base communique avec le détecteur de couleur et un dispositif utilisateur (18) pourvu d'un programme hébergé (20) qui génère une interface utilisateur permettant aux utilisateurs de fournir une entrée de commande pour le détecteur de couleur et reçoit les signaux de sortie du dispositif de détection de couleur et affiche une première image de la couleur détectée et une seconde image d'une couleur sélectionnée par l'utilisateur à côté de la première image. Les valeurs des données de couleur sont affichées et correspondent à la différence qu'il y a entre les couleurs affichées.
